The price increased several times overnight. But behind the glamor there is always something unexpected... Why do some disciples of Ji Shizong seem not very smart? Why do some people like to crawl in dark places? Why are some people who are obviously tone-deficient but not tone-deaf? Why do some alchemists hit people with alchemy furnaces... What exactly do the two doors in the story refer to? I have no idea. Are we the puppets of fate or the enforcers of fate? Is there a predetermined ending? If so, are individual efforts a joke?
